国际象棋：裁剪棋盘符号样式中的图形周围的空白

Question

考虑一下 Ulrike Fischer 的代码这里：

\documentclass{article}

\usepackage{xskak}
\usepackage{expl3}

\makeatletter
\ExplSyntaxOn
\clist_const:Nn \c_svend_figlanguages_clist {@LSB , @LSBblack}

\cs_generate_variant:Nn \clist_if_in:NnTF {NxTF}

\newcommand*\bonde[1]
 {
 \clist_if_in:NxTF \c_svend_figlanguages_clist { \cfss@figlanguage }
   { \textsymfigsymbol {p} } { #1 }
 }
\ExplSyntaxOff
  \newcommand*\cfss@king@@LSBblack  {\raisebox{-0.31ex}{\setboardfontsize{\f@size}\BlackKingOnWhite}}
  \newcommand*\cfss@queen@@LSBblack {\raisebox{-0.37ex}{\setboardfontsize{\f@size}\BlackQueenOnWhite}}

  \newcommand*\cfss@pawn@@LSBblack  {\raisebox{-0.31ex}{\setboardfontsize{\f@size}\BlackPawnOnWhite}}

\newcommand\svendusefigurine{%

\def\svend@whitelanguage{@LSB}}

\newcommand\svendusealgebraic{%
  \def\svend@blacklanguage{english}% change if needed
  \def\svend@whitelanguage{english}%
  }

\newcommand\svendusefigblack{%

黑色棋子周围的空白比白色棋子周围的空白多。是否可以裁剪黑色棋子周围的空白，使其与白色棋子周围的空白相同？

Answer 1

黑色棋子是仿制自棋盘字体的。棋盘字体的字符是二次的，这意味着它们不仅具有与小雕像不同的基线，而且侧边距也不同。对于棋子来说，这一点比其他字符更明显。您可以测量白色棋子并使用此宽度 - 您可以使用 \vphantom 来设置高度和深度。
